It was during the week of 07 December 2020 that the rockpools were fixed on a part of the quay in Ouistreham.
A total of 24 rockpools appeared there and collected the first marine microorganisms at the first tide.
The colonisation of these structures will be carried out until 2022 by the University of Caen Normandy.
